DOOR-HOLDER.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed January 11, 1908. Serial No. 410,402.

To all whom it may concern:

Be it known that I, JASPER Crms'rnnn WINN, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Door-Holders, of which the following is a specification.

The invention has reference to means for retaining a door, shutter or frame in a temporary fixed position, relatively to a portion from which such an element may move, an comprehends instrumentalities whereby an automatic release from said temporary fixed oosition may be effected at the instance of draft-effort applied to the element first mentioned.

In carrying out the above intention, suitable forms of mechanism may be adopted, within the purview of the intention, it be ing obvious, of course, that such adoptions will be of simple, inexpensive, durable and practical character. 4

As a means of more fully setting forth the invention, a construction is illustrated, embodying said invention, but which is, of course, only one of the forms in which the invention may be clothed. 1

This form comprises an element relatively to which, another element may have a reciprocatory movement, during which and simultaneously therewith, there may be a corresponding relatively rotary movement, the latter being adapted to create a lateral positioning of a member (operated by the second named element,) with relation to a member, adapted, in operation, to normally control the third member, thus affecting a relative release of the two members. Automatically operable means are employed to normally position the parts.

As a detail description of a device which embodies the above features, reference may be had to the sheet of drawing on which Figure 1 is an illustration of a portion of a closure, looking at it endwise; a retainer, partly in section disposed on a surface relative to which the closure moves, and means disposed on the closure for cooperation with the element on that surface just mentioned. Fig. 2 illustrates in section, constructive fea tures of the form set forth. Fig. 3 defines an elevation view, in illustration of the retaining device from a View point other than that previously considered, and Fig. 4c, illus trates a perspective View of a feature of the retainer.

Similar characters of reference indicate similar parts in the various figures.

Mounted in a suitable casing 5, which may be secured to a surface by fasteners 6, passing through openings in a base 7, either suitably formed on or associated with the casing 5, as shown, for instance in Figs. 1 and 3-the latter showing the casing threaded as at 8, and a base screwed thereon-is a piston 9, on an extremity of which, that extends beyond the casing 5, is formed a retaining head 10, which is adapted to cooperate with a retainer, elsewhere displayed, and more fully hereinafter to be set forth, and which head may comprise intersecting surfaces 11 and 12, the former for holding against an element of the elsewhere displayed retainer, while the latter operates to shift the position of such retainer. It is designed that the character of the holding surface 11 shall be such that at the instance of a lateral movement of the holding surface 11 and the retainer relatively, there will be a release one from the other. This lateral motion in this case, may be effected by causing the piston 9 and the casing reciprocations, and this may be accomplished by a pin-and-groove connection between the casing and the piston, and while it matters not how this is done, it may be expedient to form a helical groove 12 on the piston 9, while using as an equivalent for the pin, a

ball 18, carried in an opening 1& in the cas- 1ngthis ball, in the present instance being suitably confined, as by a cap 15 screwthreaded into the body of the casing 5.

To induce a return reciprocation between the casing and piston, a resilient member 16 is secured to each element-the casing and piston. In this connection, convenience may warrant the securing of one portion of the element 16 to the piston by a screw 17, while the other may be carried as at 18 by a cap or plug 19, seated in the casing.

Interposing the piston 9 and the casing 5, may be a combined buffer and moisture and 5 to move relatively during dust proofing element 20, which not only projection of the bolt. This bolt has a shoulder 27 upon which rests a spring 28 encircling a shank of the bolt. The upper end coil of the spring28 is bent and closed about a stud 29 on a plug 30 which closes an openingin' the casing 22. This is simply an illustration of a form of retainer which may be conveniently employed, and in no wise limits the entirety of the invention.

The operation: Contact of surfaces 12 of the head 10, with bolt 21, when the closure is moved to a position where it is desired that it should be held, causes a recedence of the bolt which permits a continuous passage of the piston 9 until the head passes'the locking line of the bolt, which automatically returns to its normal position and in juxtaposition with the surface 11 of the head 10. There is now mutual retention. Attempted diametrically opposite draft causes the piston and casing to move relatively, when, by virtue of the connection between the casing and piston, there arises a rotary movement which causes the retaining head to move laterally and out of alinement with the line of the bolt 21, when the two members are released, and thereupon the normal positions relatively of the piston and easing are automatically restablished by the intervening resilient member.

I claim:

1. A device of the kind described, comprising a fixable member, a member carried thereby and adapted for longitudinal movement with respect thereto, means for causing a rotatiy e movement of the second member while moving longitudinally, means to normally position the members, and means to engage the second member while in normal position.

2. A device of the kind described, comprising a fixable member, a member carried thereby and adapted for longitudinal movement with respect thereto, and which carries a retaining head, a spiral groove carried by one member, and a ball carried by another member whereby the moving member may be rot-atedduring movement, means to normally position the members, and means to engage the retaining head while the latter is in normal position.

3. A device of the kind described, comprising a fixable member, a member carried thereby and adapted. for longitudinal move- .ment withirespect thereto, and which carries a retaining head, means-for causing a rotative movement of the second member while moving longitudinally, means to normally position the members, means to engage the second member while normally positioned, and means to prevent dust and moisture from entering the structure.

4:. A device of the kind described, C0111- prising a fixable member, a member carried thereby and adapted for longitudinal movement with respect thereto, and which carries a retaining head, means for causing a rotative movement of the second member while moving longitudinally, a buffer between the members, a spring to normally position the members, means to en age the second member while it is normally positioned, and means to secure the fixable member in position.

In witness whereof I have hereunto set my hand in the city, county, and State of New York, this 6th day of January, 1908.
